W artykule omówiono porozumienia handlowe zawarte między Meksykiem a innymi krajami. Wyniki analizy odpowiedzi na impuls oraz współczynników natychmiastowej quasi-korelacji wskazują na znaczący wzrost synchronizacji meksykańskiego cyklu koniunkturalnego z cyklami krajów rozwiniętych oraz na istotny wzrost wrażliwości gospodarki meksykańskiej na szoki w gospodarce światowej.

In this paper we evaluate the role of trading channels in the transmission of shocks on the basis of the business cycle synchronization between the Mexican and the world economy. In order to evaluate business cycle synchronization, parameters of 2-variate VAR models for GDP growths are estimated. Measures of instantaneous quasi-correlation coefficients are calculated for the period preceding the signing of an agreement and the period of validity of the agreement.

In economics there are several complex learning themes and tasks connected with them difficult for deeper understanding of the learning subject. These are the reasons originating serious learning problems for students in the form of Virtual Environment because deeper understanding requires high level mathematical skills. Actually the most important feature for discerning this part of economics is the set of qualitative shapes emerging in discrete dynamic systems when they are undergoing iterations and/or experimentation with parameters and initial coordinates of variables. Among such shapes there are: - trajectories in evolving time; - trajectories in R2 of two variables; - cobweb portraits; - one control parameter bifurcation with first and/or with second variables; - two control parameters bifurcation in R2 (attractive basin of double controls); - cycles; - basin of attraction of two variables; - one Lyapunov’s exponent against some of control parameters; - Lyapunov’s exponents with two control parameters in R2; - absorbing area with possibility to create critical curves and/or attractors. The hope is that products of computational intelligence may help them solve such problems. Naturally, the meant complex economic problems and tasks have discrete, qualitative and nonlinear (noninvertible) nature resulting in increased level of difficulties. So with the term used in the head of this paper one has to understand narrowly: “qualitative nonlinear computational economics”. For better understanding the very nature of the problem we are using as appropriate example actual simulation of the model of new ICT products monopolies in virtual laboratory built in the routines setting dominantly in the software iDMC.
